CAN OR CONTAINER FOR VQLATiLE QILS, ueuloaac.

SPECIFICATION forming part of Letters latent No. 730,530, dated June 9,1903.

Application filed April 4, 1901.

To all whom it may concern: i

Be it known that I, CASSIUSM. GOOLD, a citizen of the United States,residing at Morris, in the county of Grundy and State of Illinois, haveinvented a new and useful Tin-'- provement in Cans or Containers forVolatile Oils, Liquids, &c., of which the following is a specification.

My invention relates particularly to means for readily sealing andunsealing the ingress and egress openings of vessels of this character;and my primary object is to provide a readily-actuated sealing devicethe parts of which are not detachable, being, therefore, not liable tobe mislaid or lost.

My invention is illustrated in convenient form in the accompanyingdrawings, in which- Figure 1 represents a broken sectional view of theupper portion of a can or vessel equipped with myimproved device, andFig. 2 a section taken as illustrated at line 2 of Fig. l.

A represents a can or jar, which may be of glass or any other suitablematerial, the same being provided in this instance with a metallic topA, secured in a well-known manner by plaster-ot-paris a. The topisprovided with the usual outlet-spout a and inletport 01?, the latterserving also asan air-vent, To give to the top greater rigidity than iscom: mon, I prefer to provide at the inner surface thereof astrengthening cross-plate b, provided with perforations 1) 19 whichregister, respectively, with the outlet at and the inlet (1?. At thecenter of-the top of the can is' journaled' a valve-carrying stem 0,passing through a packing-ring 1, confined between a shoulder 2, withwhich theupper end of the stem is provided, and the upper surface of thecan-top, said stem being provided above said shoulder with an expandedoperating-head c and at its lower end with a threaded por-I tion 0 Thelower end of. said stem has threaded connection with a spanner d, whichbears at its ends valves d (1 adapted to close the ports b 11respectively. Confined between the top of the can and the spanner is aspring 01 the tendency of which is to force the spanner downwardly,thereby depressing the valves from the openings which they con-SeriaLNo. 54.3.75- (No model trol. At the lower end of" the stem 0 isprovided a pin orstoptl which limits the downward movement of'thespanner. Adjacent to the ports bl b of the plate 12 are providedstop-pinsf, which serve to limit therotation of the spanner in twodirections. When the spanner occupies the position of the full lines inFig. 2, its rotation in the direction opposite that indicated by thearrow being limited by said stops, the valves are in position to closethe ports when the spanner is drawn upward by the rotation of thescrew-stem. When the spanner occupies the position of the dotted'linesin Fig. 2, its rotation in the direction of the arrow being limited bysaid stops, the ports are unobstructed.

The operation will be readily understood. By turning the stem 0 to theleft, assuming the can to be in an upright position and the screw to' bea right-hand screw; the spanner is released and is pressed downwardalong its stem by the spring. When the pressure ofthe valves against thelower surface of the top is released, the spanner is rotated by the stemand is carried around to the position of the dotted lines of Fig. 2,where it engages the stops. again When the stern is turned in theopposite direction, the result is to carry the spanner back to theposition of the full lines of Fig. 2;andafter engagement with the. stopsf the spanneris drawn upwardly by the screw-stem,pressing the valvesfirmly beneath the ports. The valves are preferably provided with cork'or other suitable facings, and as much pressure may be applied to themas may be desired.

The advantages arising from thisiinprovement are obvious. The can may beso securely closed as to prevent the possibility of evaporation orleakage regardless of the position of the can. Moreover, in theoperation of. opening the can, which is easily accomplished, the vent isopened at the same time that the spout is, thereby permitting the oil tohow out freely and also reducing the danger of explosion in case ofhighly volatile and inflammable oils by providing ample vent forrapidly-expanding gases.

The double movementfirst of depression and then of partialrotationprevents the valves from wearing and leaves the ingresspassageunobstructed, so that a funnel can be dropped-into place preparatory tofilling the can.

The forms of the spanner, spring, and stem may be variously modifiedwithout departure from myinvention. Therefore no limitation is to beunderstood from the foregoing detailed description, except as shallappear from the appended claims.

What I claim as new, and desire to secureby Letters Patent, is-- 1. Thecombination with a can or similar vessel provided with a port, of avalve-carrying stem extending through said can adjacent to said port, avalve carried by said stem, and connections between said parts wherebythe valve may be first depressed and loosened and then rotated in aplane parallel to the can-top away from the port through the medium ofsaid stem.

2. The combination with a vessel of the character described having anoutlet-port and an adjacent port, of a valve-carrying stem extendingthrough said vessel,and valves within said vessel and carried andactuated by said stem, said valves having a movement of depressionrelieving the pressure upon the valveseats and another movement ofpartial rotation in a plane parallel with the can-top.

3. The combination with a vessel of the character described, having aport, of a valve within said vessel and closing said port, avalve-carrier within said vessel, an operatingstem extending throughsaid vessel and having threaded connection with said valve-carrier,means for limiting the downward movement of said valve-carrier, andmeans for limiting the rotary movement thereof.

4. The combination with a vessel of the character described, having aport, of a valve within said vessel closing said port, a valvecarrierwithin said vessel, a valve-operating stem having threaded connectionwith said carrier, a spring operating to depress said valve-carrier, andmeans for limiting the rotation of the valve-carrier.

5. The combination with a vessel of the character described having twoports, of a valve-carrier within said vessel equipped with two valvesfor closing said ports, an actuating-stem extending through said vesseland having threaded connection with said valvecarrier, a spring confinedbetween the valvecarrier and the adjacent wall of the vessel and servingto depress said valve-carrier when the stem is rotated, a stop carriedby said stem and serving to limit said movement of depression, and astop carried by said vessel and serving to limit the rotary movement ofsaid valve-carrier.

6. The combination with a can or similar vessel provided with a port, ofa valve-carrying stem extending through said can adjacent to said portand provided exterior to the can with a shoulder, a packing-ringreceiving said stem and confined between said shoulder and the externalsurface of the can, a valve carried by said stem, connections betweensaid stern and said valve whereby the valve may be first depressed andthen rotated away from the port by simple rotation of said stem, and

a spring within the can and tending to depress the valve, substantiallyas described.
